Can a blown fuse cause a jump start?

Where is the fuse on a car battery?

We do plenty of jumpstarting here at the shop and have never blown a fuse yet. In addition to the fuses they replaced already, there is usually a large amperage fuse in the feed wire from the alternator to the battery. Alot of times this fuse is hidden somewhere in the wire run. If this fuse is blown, it will appear that the alternator is bad.

What to do if your alternator blows a fuse?

If this fuse is blown, it will appear that the alternator is bad. Make sure the shop has checked continuity in the feed wire from the alternator to the battery before they replace the alternator. The easiest way to do this is to simply check for battery voltage at the alternator on the large wire. Damn! Thanks for that markbob.

Can a 20 amp fuse cause a blown fuse?

The most common amperages are 15, 20 and 30, and replacing a 15 amp fuse with a 20 or 30 amp, or a 20 amp fuse with a 30 amp, may result in a blown fuse. Worse, it could cause a more severe car electrical problem, because it can cause wires to melt.

What does a fusable fuse look like on a car?

Going between the + battery terminal and the underhood fuse box should be a wire called a “fusable link”. This “link” looks exactly like a wire, but is actually a fuse. They’re designed to bubble up if they’re overpressured, but don’t always. The “link” is designed to protect all the operating circuits in the vehicle from a dramatic pulse.

Why does my motorcycle keep blowing fuses?

If fuses continue to blow after you replace them, you likely have a more serious electrical issue somewhere in the bike’s wiring. The line between the petcock and the engine can sustain damage, too, which keeps the system from operating properly.
